Searchers have now recovered 156 bodies from the waters where a South Korean ferry sank a week ago.

At the same time, relatives of the nearly 150 people still missing are pressing the government to quickly finish the recovery effort.

There is, however, a sensitive issue is looming in the background: the issue of when to bring in the cranes and begin the salvage effort by cutting up and raising the submerged ferry.

The government has warned that the work might eliminate air pockets that could be sustaining survivors.

Some relatives have given up hope of that, but others haven't.
